Hi all. I let my E39 M5 battery run down (I know, I know!)
I jumped it back up and it's been running fine mechanically.
Only weird thing is that the computer / sat nav has gone all lo tech and blue / yellow colour as compared to normal BMW black and grey etc. I'm not sure the BMW logo is showing either - generally acting weird.
Anyone else had this issue? Would like to avoid taking it in to BMW.
Thank you !
